5.2.2.1 Non-Danfoss Contactors

Non-Danfoss contactors are compatible with the VLT
Advanced Harmonic Filter AHF005/AHF 010. If using non-
Danfoss contactors for capacitor disconnect, always select
AC3-types. The current rating of the contactor must be
equal to or higher than 50% of the nominal current rating
of the AHF.
If the contactor is controlled by external equipment and
not by a specific parameter in a Danfoss frequency
converter, use contactors for capacitive switching.

The kits consist of 2 parts:
•
A top plate that prevents dirt and vertically
falling drops of water from entering the filter.
®
•
A terminal box enclosing the terminals and
connections, thus ensuring touch-safe terminals.
The terminal cover is prepared for installation of a
contactor for capacitor disconnect.
Spacers must be used at IP21 top cover at enclosure sizes
with:
•
External fan type 1.
•
External fan type 2.
•
Internal fan type 2.
